Sure enough, [Brian] Barnard, a civil rights attorney, has brought a lawsuit challenging Utah’s ban on polygamy. And some legal experts say the case could have a fighting chance because of the Supreme Court’s gay-sex ruling.

Can you hear it; the sound of American society sliding further down that slippery slope? It’s almost deafening.
